Sorry, but while there's "no crying in baseball" there should be no sympathy in football....the other team, even in college, is making millions for showing up and playing....it's the fault of their coaches and players if they can't keep up.
I don't believe in the philosophy of playing nice and running into the line 3 times and punting or kneeling down on the other team's 5 yard line because you think they'll be mad if you score again.
Coaches should teach their young men to play with the pedal down till the final horn sounds, but without gloating and showboating. When I coached in high school, we played our starters until the team we were beating put in their subs...running up the white flag...then we'd call time out and put in all our scrubs...and there was nothing wrong with throwing the ball on 3rd and long no matter what the score was. Do you think the losing team's 2nd and 3rd team defensive players who finally get on the field want to stand there and watch the offense kneel down??!! NO, they want to compete.
Football isn't war governed by the Geneva Convention....it's a game, a sport, a competition, and teams that know learn how to put other teams away eventually lose a few games they had in hand. Any coach watching the scores from yesterday when teams were routinely coming back from 20 point deficits should have played the entire 60 minutes.
